A re-usable alternative to putting a styrofoam cup on your ice coffee in order to prevent the puddles of water caused by condensation. I made these to fit medium and large iced coffee cups from Dunkin Donuts, but they also fit on the generic, re-usable, hard plastic travel ice coffee cups we have.
Basically, a big sock with a bottom for your ice coffee cup. If you can knit a sock you can knit these.
I used just under 20 grams of yarn per koozie so it’s a great way to use up scraps.

This pattern is the taller version shown in the mulit colored stripe. This pattern has been test knit by me only. The patterns are text only.
